LEDVANCE QUICKTRONIC® HELIOS™ QT2X54/277PHO-DIM/49674 Electronic Dimming Ballast, FP54T5HO Lamp, 54 W, 277 VAC

PROStart ballasts provide optimum starting conditions to provide upto 100,000 switching cycles for use on occupancy sensors and building control systems. QUICKSENSE® ballast technology helps to protect against overheated bases and sockets, as well as cracking of the glass wall, and uses dynamic end-of-lamp-life sensing, over the entire dimming range, to avoid false shutdowns caused by some static sensing methods. QUICKSENSE® ballast technology will auto reset when the end-of-life lamps are replaced with new ones. QUICKTRONIC HELIOS T5HO ballasts are available in a 30 x 30 mm profile, and PENTRON lamps are designed to provide peak performance at 35 deg C fixture ambient, allowing for smaller and more innovative fixtures.
